Raspberry Pi is a versatile and powerful tool, popular among hobbyists, educators, and developers. Whether using it for personal projects, prototyping, or as a learning tool, coding remotely on your Raspberry Pi can greatly enhance your workflow. Visual Studio Code Raspberry Pi (VS Code), a lightweight but powerful source code editor, offers excellent support for remote development on Raspberry Pi. This guide will walk you through setting up and coding remotely on Raspberry Pi using VS Code.
Why Code Remotely?
- Convenience: Access your Raspberry Pi without needing to be physically near it.
- Efficiency: Utilize your main computer’s resources while coding.
- Flexibility: Switch easily between projects and environments.
Prerequisites
To get started, you’ll need the following:
- A Raspberry Pi with an operating system installed (Raspberry Pi OS is recommended).
- A stable network connection to your Raspberry Pi.
- SSH enabled on your Raspberry Pi.
- Visual Studio Code installed on your main computer.
- The “Remote – SSH” extension is installed in Visual Studio Code.
Step-by-Step Guide to Set Up Remote Coding
Step 1: Enable SSH on Your Raspberry Pi
If SSH isn’t already enabled on your Raspberry Pi, you can do so by following these steps:
- Open the Raspberry Pi Configuration tool from the main menu.
- Navigate to the Interfaces tab.
- Enable SSH.
- Click OK to apply the changes.
Alternatively, you can enable SSH via the command line by running:
bash
Copy code
sudo systemctl enable ssh
sudo systemctl start ssh
Step 2: Find Your Raspberry Pi’s IP Address
You’ll need the IP address of your Raspberry Pi to connect remotely. You can find it by running:
bash
Copy code
hostname -I
Take note of this IP address, which you will use to establish a connection.
Step 3: Install Visual Studio Code and the Remote – SSH Extension
Ensure that you have Visual Studio Code installed on your primary machine. Once installed, add the Remote – SSH extension:
- Open Visual Studio Code.
- Go to the Extensions view by clicking the Extensions icon in the Activity Bar on the side of the window or pressing Ctrl+Shift+X.
- Search for “Remote – SSH” and click Install.
Step 4: Connect to Your Raspberry Pi
Now that you have everything set up, it’s time to connect to your Raspberry Pi:
- Open the Command Palette in Visual Studio Code by pressing Ctrl+Shift+P.
- Type “Remote-SSH: Connect to Host” and select it.
In the prompt, enter the SSH connection string in the following format:
kotlin
Copy code
pi@<your_pi_ip_address>
For example:
CSS
Copy code
pi@192.168.1.100
- If it’s your first time connecting, you might be prompted to accept the host’s key fingerprint and enter your Raspberry Pi’s password.

Step 5: Open a Project on Raspberry Pi
Once connected, Visual Studio Code will open a new window where you can start working on your Raspberry Pi’s file system. You can open an existing project or create a new one directly on your Raspberry Pi.
Step 6: Install the Required Extensions
To enhance your coding experience, install any necessary extensions that you typically use for coding in Visual Studio Code, such as Python, Node.js, or C++. These will work remotely on your Raspberry Pi, just as on your local machine.
Step 7: Start Coding!
Conclusion
Coding remotely on your Raspberry Pi using Visual Studio Code offers flexibility, efficiency, and convenience. By following the steps outlined in this guide, you can set up a seamless remote development environment and unlock your Raspberry Pi’s full potential while leveraging the powerful features of Visual Studio Code.
